Change Details

eventstreams (and eventstreams-internal) used a version of `service-template-node` that is so old that the [[ https://github.com/wikimedia/service-template-node/commit/6c1e6c087971e789e82532d013b750d1cae05fb1 | router metrics ]] are in a `Gauge` format. The current version of `service-template-node` and `service-utils` uses `Histogram` instead. All express router metrics in [[ https://grafana.wikimedia.org/d/znIuUcsWz/eventstreams?orgId=1&refresh=1m | Grafana ]] must be updated.

All express router metrics in [[ https://grafana.wikimedia.org/d/znIuUcsWz/eventstreams?orgId=1&refresh=1m | Grafana ]] must be updated. Here is what I think is the safest way to go about this: ```lang=markdown 1. Deploy eventstreams to codfw 2. Wait and see which Grafana charts go to 0 3. Update those charts, see if the data comes back 3a. Track what I changed on this ticket just in case we have to revert 4. Deploy eventstreams to eqiad ```
